Some recent GEOTRACES science findings are reported below.
The results evidence that the effect of advection cannot be neglected in areas where a conjunction of significant horizontal dissolved aluminium gradients and significant horizontal currents is found.
One of the main consequences of this work is that manganese should be included in ocean-climate models, more particularly to improve the accuracy of their predictions in this area.
Homoky and co-workers determined the isotope composition of dissolved iron profiles in shallow surface sediments of the South Atlantic Uruguayan margin…
Oka and colleagues demonstrate that the global distribution of REE can be reproduced by considering the internal cycle associated with reversible scavenging and external REEs inputs around continental regions.
This study demonstrates the importance of biology and ecology to understanding iron biogeochemistry.
This study provides one of the first mechanistic explanations for Last Glacial Maximum deep ocean deoxygenation.
Mellett and Buck present the concentrations of bioactive trace metals (Fe, Cu, Mn, Zn, Co, Ni, Cd, and Pb), Fe-and Cu-binding organic ligands, and electroactive Fe-binding humic substances in the eastern Gulf of Mexico.
Twenty seawater profiles and twenty core-top 231-protactinium and 230-thorium analyses were realised by Ng and colleagues along five depth transects across the northern tropical Atlantic open ocean.
Using available observations of dissolved copper, artificial neural networks, and an ocean circulation inverse model, authors calculated a global estimate of the 3-dimensional distribution and cycling of dissolved copper in the ocean.
